AI Technical Summary
Existing column-type heat meter base meters are prone to measurement errors during use due to the complex flow characteristics of water flowing through pipe components, and are difficult to effectively prevent loosening, affecting measurement accuracy and stability.
A quick-release column-type base meter for heat meters is designed. By arranging a symmetrical mounting shell and a half-split screw on the pipe assembly and utilizing a combined structure of a locking nut and a limit rod, the friction force is enhanced to prevent the base meter from rotating loose, and the connection stability is enhanced by a flexible extrusion part and a clamping structure.
It effectively prevents the loosening of the column-type base of the heat meter, improves the stability and accuracy of measurement, expands the scope of application, and adapts to the installation requirements of different base meters.
